Unlike other eye conditions, such as myopia or astigmatism, presbyopia is specifically related to the eye aging, and the lens of the eye losing its flexibility. The lens is composed of proteins, and it is thought that overtime, as the eye ages, the lens looses proteins, making the lens more rigid. As well, the associated muscles of the eye have aged, and have lost flexibility, and are unable to help the lens flex and focus. The result is the eye is unable to focus on things that are close.
This aging of the eye is most noted around the age of 40. You may notice that you have to hold things further away in order to read fine print. Unfortunately, presbyopia is unavoidable, as it simply is the result of the eye aging.
Almost everyone will develop presbyopia, so if a person also has another eye condition such as myopia (nearsightedness), hyperopia (farsightedness) or astigmatism, the conditions will combine. Individuals that are nearsighted (myopia) may have fewer problems with presbyopia than those that are farsighted or those with astigmatism.Treat your eyes to an exam
